Application filedhiay 23, 1908. Serial No. 4%,559.

T all whom it may concern: l Be it known that I, HOWARD C. BROWN,citizen of the United States, residing at Chi l cago, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Vibratory Massage Apparatus, of which the following is aspecification. 1

This invention relates to electric vibratory l massage apparatus, andespecially to that class of implements which are held in the hand whilebeing i'nanipulated or operated.

Common appliances of this kind have the coils of the magnet placed onopposite sides of the rotary armature, and this causes the entire weightof the coils and magnet to be I placed at the end of the handle, whichmahes l the apparatus cumbersome and heavy and 1 tiresome to handle. I

The object of the present invention is to l remedy this condition by anovel construction characterized by the fact that the coil and magnetextend lengthwise in the hollow handle, and so the weight is balanced orevenly distributed, and the implement can be used without fatigue andgenerally more conveniently.

The invention is illustrated in the acconii p anying drawings, in whichi Figure 1 is a side view of the implement. i Fig. 2 is a horizontalsection. Fig. 3 is a 1 vertical, section.

The implement has a suitable inclosingl casing or cover, consisting of ahollow head i 6 and a tubular handle 7, the former having a taperedextension 8 on the under side. i The motor coil is indicated at 9 andits core g at 10. These are located or extend lengthwise within thetubular handle 7 The field 1 or pole piece 11 at the front end isattached l to the core at one end and is curved in substantiallysemi-circular forin around one side of the armature 12, and the otherpole or 1 field piece 1.3 is connected to the rear end of the core andextends thence along the side 1 of the magnet to the front end thereof,and is curved around the opposite side of the armature, as shown at 14,the curved ends 11 and 1e fitting within the circular part of the head6. The armature is mounted upon a spindle i 15 which also carries thecommutator 16 on its upper end, and on its lower end it has an eccentric17 which works Within a yoke 18 offset from the upper end of a lever 19which 1s pivoted on a screw 20 to the side of the tubular extension 8,and at the lower end the lever has an offset arm 21 which. carries theapplicator or pad 22 which is applied to the surface to be massaged.

By the construction shown the heavier parts of the device are containedin or extend along within the handle, instead of being grouped at oneend thereof. This enables the instrument to be handled with much morefacility than would otherwise be the case, and enables the pressureapplied to the applicator to be nicely controlled. The rotation of thearmature vibrates the lever 19 and so vibrates the pad or appiicator inan obvious manner, the eccentric 17 working be tween the arms of theyoke 18 and so causing the lever to vibrate on its pivot 20.

I claim:

1. A vibratory massage implement, raving an outer casing comprising ahollow head and handle arranged at an angle to each other, and anelectric motor the core and field coil of which extend lengthwise in thehandle, and having pole pieces extending from opposite ends of the coreand around opposite sides of the head, and an armature and its shaftwithin the head and between the pole pieces, with its axis at an angleto that of the coil.

2. A vibratory massage implement having a casing comprising a hollowhandle and head, an electric motor field coil and core extendinglengthwise in the handle and having pole pieces at opposite endsextending into the head, the pole pieces connected to the rear end beingbent around and extending along beside the coil to the front endthereof, and an armature and its shaft located between said pole pieces,in the head of the casing with its axis at an angle to that of the coil.

In testimony whereof I aflix my signature, in presence of two witnesses.
